Quantum illumination reveals phase-shift inducing cloaking
(Nature Publishing, 2017-08-24)
In quantum illumination entangled light is employed to enhance the detection accuracy of an object when compared with the best classical protocol. On the other hand, cloaking is a stealth technology based on covering a ...
Supervised Quantum Learning without Measurements
(Nature Publishing, 2017-10-20)
We propose a quantum machine learning algorithm for efficiently solving a class of problems encoded in quantum controlled unitary operations. The central physical mechanism of the protocol is the iteration of a quantum ...
Approximate Quantum Adders With Genetic Algorithms: An IBM Quantum Experience
(De Gruyter Open, 2017-07)
It has been proven that quantum adders are
forbidden by the laws of quantum mechanics. We analyze
theoretical proposals for the implementation of approximate
quantum adders and optimize them by means
of genetic algorithms, ...
Degree of Quantumness in Quantum Synchronization
(Nature, 2019-12-27)
We introduce the concept of degree of quantumness in quantum synchronization, a measure of the quantum nature of synchronization in quantum systems. Following techniques from quantum information, we propose the number of ...
Quantum autoencoders via quantum adders with genetic algorithms
(IOP Publishing, 2019)
The quantum autoencoder is a recent paradigm in the field of quantum machine learning, which may enable an enhanced use of resources in quantum technologies. To this end, quantum neural networks with less nodes in the inner ...
The TrapSensor Facility: an Open-Ring 7 Tesla Penning Trap for Laser-Based Precision Experiments
(IOP Publishing, 2019-02-28)
A Penning-trap facility for high-precision mass spectrometry based on a novel detection method has been built. This method consists in measuring motional frequencies of singly-charged ions trapped in strong magnetic fields ...
Parity-Assisted Generation of Nonclassical States of Light in Circuit Quantum Electrodynamics
(MDPI, 2019-03-13)
We propose a method to generate nonclassical states of light in multimode microwave cavities. Our approach considers two-photon processes that take place in a system composed of N extended cavities and an ultrastrongly ...
Quantum Artificial Life in an IBM Quantum Computer
(Springer Nature, 2018)
We present the first experimental realization of a quantum artificial life algorithm in a quantum computer. The quantum biomimetic protocol encodes tailored quantum behaviors belonging to living systems, namely, self-replication, ...
Scalable quantum memory in the ultrastrong coupling regime
(Nature Publishing, 2015-03-02)
Circuit quantum electrodynamics, consisting of superconducting artificial atoms coupled to on-chip resonators, represents a prime candidate to implement the scalable quantum computing architecture because of the presence ...
Digital Quantum Simulation of Spin Models with Circuit Quantum Electrodynamics
(American Physical Society, 2015-06-17)
Systems of interacting quantum spins show a rich spectrum of quantum phases and display interesting many-body dynamics. Computing characteristics of even small systems on conventional computers poses significant challenges. ...
